OK. I'm too lazy to look it up, so what's the difference between "arteriosclerosis" and "atherosclerosis." Are they interchangeable? They both refer to the narrowing of some tube or another; the former seems to point to arteries, but what's the latter talking about?

NOUN:A form of arteriosclerosis characterized by the deposition of atheromatous plaques containing cholesterol and lipids on the innermost layer of the walls of large and medium-sized arteries.ar∑te∑ri∑o∑scle∑ro∑sis (šr-tÓr--skl-rss) KEY

NOUN:A chronic disease in which thickening, hardening, and loss of elasticity of the arterial walls result in impaired blood circulation. It develops with aging, and in hypertension, diabetes, hyperlipidemia, and other conditions.

Beck123 said he was lazy, so I took the trouble to copy the difference in meaning according to Am.Her. for those two words. Roughly, I don't like to do more than is needed either. As 123 is a native speaker he won't have trouble with pronunciation anyway. aside to *123.. I mentioned Onelook so you can do your own search.

What's more critical is that I don't know what diacriticals means nor the KEY.

Diacriticals are the funny hats and slippers that some letters put on when visiting foreign lands, e.g., ā (an a with a macron), ă (an a with a breve), ą (an a with a ogonek), and č (a c with a haček). &c, &c.

The Key, I believe is a pronunciation key which maps symbols to sounds in a dictionary.
